How to prove that social insurance is included in wages?

1. Payroll: You can clearly see the detailed information of salary composition through the payroll, which should include the deduction amount of social insurance and the actual salary received by individuals. You can ask the employer or the financial department for the relevant payroll as proof materials.

2. Labor contract or labor relationship certificate: A labor contract or labor relationship certificate usually clearly stipulates the deduction and payment of social insurance. By consulting the labor contract or labor relationship certificate, you can find the relevant clauses that confirm that the salary includes social insurance.

3. Social security payment records: You can ask the social security agency or the human resources and social security department for social security payment records, which will list the social security payment of each employee in detail. Social security payment records can be used as strong evidence to prove that employees' wages include social insurance.

4. Letter of proof from the employer: You can ask the employer to issue a letter of proof, clearly stating that social insurance is included in the salary for payment.
